3 Claims.

This invention relates to air conditioning conduit systems and is a division of application Serial No. 289.749 filed August 12, 1939.

The general object of the invention is to provide a baseboard structure for accommodating an air supply line, a fluid supply line, a fluid return line, and a drain line, the temperatures of said lines normally being difierent.

A feature of the invention resides in the provision of a baseboard structure adapted readily to be assembled and having a simple and inexpensive arrangement affording easy access to lines within the structure for inspection and repair.

Another feature of the invention resides in the provision of novel interconnecting elements forming a baseboard structure which may be arranged to connect with vertical risers containing air and liquid lines, whereby ready connections may be made from said lines to units located at a distance therefrom, and attractive concealment of connecting lines accomplished.

These and other features and advantages are more apparent from the following description of one form of the invention to be read in connection with the accompanying drawing in which Fig. 1 is a view in vertical section of a baseboard construction adapted to contain and conceal laterally extending air, water and drain conduits, taken on the line I-I of Fig. 2;

Fig. 2 is a view in perspective of a corner of an enclosure served by a baseboard construction in accordance with the invention; and

Fig. 3 is a view in perspective of a baseboard spacer element.

Considering an air conditioning system of the type disclosed in copending application Serial No. 289,749, filed August 12,1939, of which this is a division, vertical risers are normally employed through which air and water conduits run to various levels of the enclosure to be conditioned. Obviously, the vertical risers will not always be in the immediate vicinity of local units located on different levels or floors of the enclosure. Therefore, it will be required to run short lateral connections from the conduits in the vertical riser to the local units. In order that these lateral extending connections may be concealed from view, there is provided the baseboard arrangement illustrated in Figs. 1-3.

As shown, a plurality of brackets I86 are sepositioned the downwardly extending flange I89 of a baseboard cover piece I90. The lower portion of the cover piece is received within a pocket formed between an upwardly extending leg I9I of the bracket and a belled portion I92 of an upwardly extending member I 93 suitably secured in any desired manner to the leg I9I of the bracket. Within the space thus formed there is also inserted the downwardly extending flange I94 of a base protecting plate I95 formed of suitable material adapted to withstand the corrosive action of cleaning agents which might come in contact therewith when the floors of the conditioned enclosure are cleaned. Mounted within the channel formed by the cover plate I is a drain trough I96 secured, as by screws I91, to the,

brackets I88. Over the drain pan I96 is positioned the laterally extending air connection 54 andthe water connections 66 and IOI. Thus, any moisture which might possibly be precipitated within the baseboard conduit is adapted to be caught by the drain pan I96, which may deliver the condensed moisture to drain pipe H8 as by means of a suitable connection I98. It will be appreciated that the cover piece of the baseboard assembly may be removed very readily to provide immediate access to the lateral air and water connections. Also, the baseboard assembly may be installed very quickly and conveniently and with the assurance that the assembly after completion will provide a finished and attractive appearance and will efl'ectively conceal the lateral pipes connecting the unit with the vertical riser.

When it is necessary to extend the lateral connections to a wall or partition, this may be accomplished neatly by means of the finishing piece I99 illustrated in Figs. 2 and 3. The finishing piece may be used in conjunction with a conventional wood molding 208 so that the finished assembly will be entirely attractive as well as mechanically satisfactory.

I claim:

l. A baseboard structure for housing air. liquid and drainage lines serving air conditioning units located remotely from a riser housing such lines, comprising a first element in the form of a bracket having an upright leg arranged to be attached to a wall, the top extremity of said leg being belled and a horizontal leg arranged to rest upon the floor, the horizontal leg having an upwardly extending flange, a second element resting upon the fioor and secured to said flange, said second element being belled at its upper extremity to form a pocket between the belled portion and the upper extremity of the flange, a

third element having one extremity resting upon the floor and another extremity fitting within said pocket, and a cover plate, said cover plate having an upper edge adapted to be slid into the space between the belied portion of said upright leg and the wall to which the upright leg is attached, the lower edge of the cover plate being adapted to be slid into said pocket.

2. In a baseboard structure according to claim 1 a drain trough attached to the upright leg of said first element, said drain trough dividing the space bounded by the cover plate and bracket into an upper compartment and a lower compartment. an air conduit, a liquid supply conduit and 'a liquid return conduit, all said conduits being located in the upper compartment, a drain conduit located in the lower compartment, and a drain connection between said trough and the drain conduit.

3. In combination with a baseboard structure according to claim 1, a finishing piece. said piece having a horizontal upper side with one edge contacting the baseboard over that portion of the cover plate fitting within said belled portion, a vertical side having one edge resting upon the floor, said vertical and horizontal sides forming a continuous surface from the floor to the baseboard. an inner edge to said piece fitting the contour of the cover plate, the vertical side oi said piece being arranged to serve as a supporting side for a base molding employed to impart a finished appearance to a partition at the floor level WILLIS H.
